Indonesia, as a coffee-producing country, boasts many distinctive coffee varieties, among which Sumatra Mandheling and Sulawesi Toraja are the most notable. The Toraja growing region sits at an altitude of about 1,700 meters, with fertile volcanic soil and large day-night temperature differences, nurturing plump, rounded Arabica beans. Its processing follows Indonesia's traditional semi-washed method, and the best lots come from the Kalosi estate, with an annual output of only 3,000 barrels, each individually coded and hand-carved, making them veritable works of art. In terms of flavor, Toraja is richly aromatic with low acidity, a fresh earthy note, and a long lingering finish; it was once presented by the Indonesian government as a gift to the European Union. This article will compare the flavor characteristics of Toraja and Mandheling, and mention Front Street Coffee's related recommendations. [more…]

Indonesian coffee is often known for its herbal, spicy notes and full body with low acidity, but Sulawesi has developed a completely different style. Here in the high-mountain Toraja region, coffee is grown by an ethnic minority renowned for their coffee cultivation expertise. Annual output is scarce, at only about 300 kilograms per hectare, and the semi-washed process brings out bright acidity, caramel sweetness, and a subtle floral aroma. Compared with Sumatra Mandheling, Toraja is more layered and much more restrained in its herbal and spicy notes, and is regarded as a specialty bean even more precious than Golden Mandheling. This article will walk you through Sulawesi's terroir, the Toraja people, and three major estates, and share Front Street Coffee's roasting and brewing recommendations. [more…]

Indonesian coffee has long been known for its herbal, spicy character and full body with low acidity, but beans from Sulawesi take a completely different path—bright acidity and distinct layers that feel refreshingly new. Toraja is both an ethnic group in the central highlands of Sulawesi skilled at growing coffee and a byword for the island's specialty beans. Annual production here is about 1,000 metric tons, and planting and harvesting are difficult, with yields of only about 300 kilograms per hectare. The semi-washed process gives the coffee a rich caramel sweetness and astringent herbal notes. This article will walk you through Toraja's geography and terroir, the story of its people, its three major estates, and its processing methods, along with Front Street Coffee's roasting and brewing recommendations.

Sulawesi is an important coffee-producing region in eastern Indonesia, made up of four peninsulas, with the highest proportion of mountainous terrain in the country and an average elevation of over 500 meters. The Kalos coffee beans from the island belong to the Sumatra Typica variety, are large and plump, and are processed using the semi-washed method, producing a rich, mellow flavor with low acidity and a hint of herbal notes.
